    Alternative fuels for aviation

    DLR's ILA exhibit shows two flames, one fuelled by conventional kerosene and one by a GtL fuel. It is easy to see that the two fuels differ in the amount of soot they produce: because of its greatly reduced number of aromatic hydrocarbons, the GtL fuel is sooting a great deal less.

In the future, fuels based on natural gas (gas-to-liquid, GtL) or biomass (biomass-to-liquid, BtL) will become more and more important as resources grow scarce and conventional kerosene becomes more expensive. Moreover, these synthetic fuels offer the option of purposefully modifying their composition in order to optimise their combustion properties and their pollutant emissions, independently of the engine design.
